A big part of why the game works so well is its writing. Though Observer only shows a thin slice of its dystopian world, the information given is still pivotal and the added level of replayability pushes the number of hours you can sink into the game well past the roughly 6 hours it takes to finish the main case.
I primarily focused on the core storyline at hand but there are several other cases to be investigated in the game and all offer just a little bit more information on the dark and unforgiving city outside. One day Daniel gets a call from his estranged son Adam and when he goes to find him gets wrapped up in several mysteries unfolding within a rundown apartment building and its surrounding areas. You play as Daniel Lazarski an investigator who can tap into people's minds using a Dream Eater also known as an Observer.
Observer: System Redux is set in the human-augmentation-filled cyberpunk year of 2084.
